The present invention provides new types of synthetic turf. The synthetic turf includes a pile fabric having a backing (1) and tufts (2) projecting therefrom. In one embodiment, at least a number of the tufts are made of a composite yarn formed by at least one fibrillated yarn (6) together with a number of individual filament yarns (7), in particular with so-called monofilament or monotape yarns. The fibrillated yarn and the individual filament yarns are preferably made of polyethylene so that t...

A synthetic rectifier comprises a MOSFET and a control circuit to turn the MOSFET off and on as a synchronous rectifier. The control circuit senses the current through the synthetic rectifier, and in particular is responsive to the rate of decrease of the current so as to anticipate when the current goes to zero and turn off at that instant. The control circuit also senses the voltage across the synthetic rectifier, and in particular is responsive to the rate of decrease of the voltage so as to ...

Compositions of the current invention are directed toward inhibiting the growth of microorganisms, particularly fungi. The compositions consist of chemically-synthesized antibiotics comprising certain amino acids. Methods of identifying particular antibiotic compositions from libraries of such compositions are disclosed. In addition, methods for preventing microbial growth in plants and animals are disclosed.

A synthetic wood material and method are disclosed, including providing a plurality of continuous glass fibers oriented substantially in the longitudinal axis and coated with a resorcinol modified phenolic resin binder substantially free from catalyst. In one aspect, the synthetic wood material is oxidatively treated to restore color. In one aspect, the fibers and binder are precoated with a furfuryl alcohol resin prior to the pultrusion step to form the synthetic wood.

A synthetic grass surface comprising widely spaced rows of ribbons and the ribbons having a length about twice as long as the spacing between the rows of ribbons. A particulate material is laid on a matrix of the synthetic grass, and the thickness of the particulate material is as least two-thirds the length of the ribbons.

By achieving an extruded, foamed core formed from plastic material peripherally surrounded and integrally bonded with a plurality of cooperating synthetic, plastic, extruded, outer layers, a unique, multi-component, multi-layer synthetic closure is provided which may be employed as a bottle closure or stopper for any desired product, whether the product is a liquid, a viscous material, or a solid distributed in a bottle or container and dispensed through the open portal of the container neck. Th...

The invention is directed to synthetic receptor(s) which comprises a polyfunctional organic template covalently linked to two or more oligomers which may independently be the same or different and may independently be straight chain, cyclic or branched. The template may be linked to an identifier which uniquely defines the synthetic receptor. The identifier is a stable chemical molecule or a plurality of stable chemical molecules distinguishable and detectable to picomolar levels or may be an ol...

A synthetic cornea for placing in a recess formed in the cornea, the recess opening out into the anterior face of the cornea so as to leave Descemet's membrane intact. The synthetic cornea comprises a piece (42) of flexible transparent material having an axis of circular symmetry and presenting an anterior face (44) in the form of a spherical cap of radius Ra and a posterior face (46) in the form of a spherical cap of radius Rp, the central zones of the two faces being separated by a distance e,...

Synthetic lubricating oils having a predetermined alkylaromatic structure are prepared from a mixture of mono- or dialkenyl benzene with an aliphatic olefin by free-radical reaction in the presence of ditertiary-butyl peroxide, for example. Equivalent napthalene derivatives may be substituted for the dialkenyl benzene. The oils that are formed exhibit a high Viscosity Index, and a low pour point. The viscosity of the synthetic lube stock produced may be controlled by changing the amount of perox...

Synthetic elements for enhancing expression of genes in plant cells are disclosed. These include a promoter with a "TATA to start" sequence containing 64% or greater GC content and an synthetic upstream element incorporating several OCS binding motifs and novel flanking sequences. Upstream activating regions (UARs) are also disclosed that can further increase the constitutive transcriptional activity when they are operably linked to said promoter and/or the synthetic upstream element. In particu...
